Abstract: Disclosed is a method that may include hosting, by a virtual machine manager of a local machine, a virtual machine having a device driver. The method may include obtaining, by the virtual machine manager, from a stub driver on the remote machine, information about the I/O device on the remote machine. The I/O device on the remote machine may be bound to the stub driver on the remote machine. The method may include instantiating, by the virtual machine manager, a virtual I/O device on the local machine corresponding to the I/O device on the remote machine. The method may include collaborating, by the virtual machine manager, with the stub driver on the remote machine to effectuate a real access to the I/O device on the remote machine for an access to the virtual I/O device by the device driver on behalf of a program on the local machine. Other embodiments may be described and claimed.
